Made in Germany

The EOS Mythos S35 is manufactured in Germany using premium stainless steel components and engineered for long-term durability, consistent performance, and architectural integration. EOS is recognized globally for precision sauna engineering and uncompromising build quality.


Authentic Finnish Sauna Experience

The Mythos S35 uses a large rock mass positioned above the heating elements to maximize stored heat and create powerful, evenly distributed steam. When water is gently poured over the stones, heat radiates naturally throughout the cabin, delivering the traditional Finnish sauna experience.

 


Note: Control unit is sold separately. We recommend pairing the EOS Mythos S35 with an EOS EmoTec D/H or EOS Touch 3 control unit to ensure proper operation and heating period limitation.

Our Scandinavian outdoor saunas, shipped from our Canadian warehouse, are delivered right to your curb. We'll call you when your sauna is ready to ship and then email you the tracking details. The transport company will then contact you to schedule delivery once it reaches their local terminal.

Included with the delivery:

Sauna Crate

You'll receive a crate with the sauna materials. The delivery driver may assist in lowering the crate, but you'll need tools to open it and at least two people to unload the components. This typically takes about 30 - 45 minutes.

Glass Window (if applicable): 

If you've ordered a special glass back, it'll arrive on a separate pallet. We try to synchronize the delivery of both items, but they may come separately. Check and note any missing items on delivery paperwork.

Sauna heater, rocks and controls:

When shipped with your sauna, they will arrive on a separate pallet. If they’re shipped directly from the manufacturer, we'll provide tracking information and coordinate the delivery timing of the heater with your sauna.

Accessories:

Basic sauna accessories will arrive with your sauna. Other items like LED lights or salt panels are shipped separately and may arrive without needing a signature.

Delivery Paperwork:

Before signing, ensure all items listed are received and take photos of the crate/pallets. This helps us assist you if there are missing or damaged items.

* If you're located in a remote area or a place where standard delivery trucks might have difficulty accessing, please inform us. We'll work out a specialized delivery plan for you, though this may require additional shipping charges. *
